CONNECTION-SLEEVE FOR GABLES.

Specification of Letters Patent.

Patented Nov. 20, 1917.

Application filed November 29, 1816. SerialNo. 134,18?

To-aZZ whom it may concern:

Be it known that I, Janus T. MADIGAN, a citizen of the United States, residing at Colorado Springs, in the. countyof El Paso and State of Colorado, have invented certain new anduseful Improvementsin Connection-Sleeves for Cables, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in connection. sleeves for cables such as employed in connection with telephones;

and it is an object of the invention to provide a device of this general character having novel and improved means whereby the adjacent ends of the cable may be effectively connected one to the other and whereby the connected portions of the wires are effec tively protected against the elements.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved connection sleeve whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein is disclosed a figure partly in elevation and partly in section illustrating a connection sleeve constructed in accordance with an embodiment of my invention.

As disclosed in the accompanying drawings, AA denote the meeting end portions of a cable of conventional construction and each of which includes the lead tubing I through which the wires l/V are directed.

In effecting a joint in accordance with my present invention, the free ends of each of the tubes L are bent outwardly to afford substantially an annular flange 1, and said free ends of the cables are spaced apart a distance sufiicient to permit the requisite tying of the wires IV disposed through each of the tubes.

Mounted upon each of the cables C is a conical sleeve 2 of predetermined dimensions and which is adapted to be positioned in close proximity to the flange 1, and interposed between said flange 1 and the adjacent end of the sleeve 2 is a washer or gaslret 3 of'suitable material and which is employed to render the connectionbetween the sleeve 2 and flange 1 substantially air and moisture tight.

Also mounted. upon each of the cables C.

is an .outer sleeve 4 adapted to snugly receive the first mentioned sleeve 2 and which has its inner end provided with an internally threaded annular flange 6 with which is engaged a peripherally threaded end portion of the cylindrical or tubular member 5 adapted to bridge the space between the flanges 1 of the cables or the adjacent ends of said cables. It is also to be noted that the gasket 3 hereinbefore referred to coacts with the outer sleeve 4: and the cylindrical or tubular member 5 in order to assure the connection between said last two members also air or moisture tight. It is to be noted that the tubular or cylindrical member 5 is of such a length as to permit the adjacent extremities of the wires W of the cable end portions to be tied or connected one to the other.

It is also to be noted that the outer end of eachof the outer sleeves 4 is of such a diameter as to overlie the outer end of the sleeve 2 so that the same is effectively held against movement longitudinally of its coacting cable in a direction away from the flange 1.

From the foregoing description, it is thought to be. obvious that a connection sleeve constructed in accordance with my invention is of an extremely simple and com paratively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish llO ing each of the cables and snugly receiving the first named sleeve, the outer end of said second named sleeve being of a diameter less than the adjacent end of the first named sleeve whereby said second named sleeve and flange of the tube hold said first named sleeve against movement longitudinally of the cable, the inner end of said second named sleeve being provided With an internally threaded annular flange, a cylindrical member detachably interposed between the second named sleeves, the opposite end portions of the cylindrical member being peripherally threaded for engagement with the internally threaded flanges of the second named sleeves, and a gasket interposed between each of the flanges of the inclosing tubes and its adjacent inner sleeve, said gasket being also interposed between an outer sleeve and the coacting end portion of the intermediate cylindrical member.

In testimony whereof I hereunto affix my signature in the presence of tWo Witnesses.

JAMES T. MADIGAN.
